Title: Slime discharging for mud-water excavation work
Inventor: OKI TADAKATSU
IPC: E02D15/06
Filed: 1986-02-20
Abstract: PURPOSE:To suck up and discharge slime by jetting compressed air into a sludge sending pipe. CONSTITUTION:After mud-water excavation, a sludge sending pipe 6 having an air injector 12 projectionally provided inside is inserted into a floating layer 3 containing diffused slime on the bottom of a pit. Compressed air from a compressor 10 is jetted through the injector 12 into the pipe 6, where the slime is sucked into the pipe 6 and discharged to the outside of an excavated pit 1. The deterioration of concrete quality due to the presence of slime can thus be prevented, and the cost of discharging slime can be reduced.

Title: Ashing system
Inventor: SAKIYAMA TSUGIO
IPC: H01L21/027
Filed: 1987-02-18
Abstract: PURPOSE:To prevent the positional displacement of a substrate to be treated by flowing out a gas onto the surface of the substrate to be treated so as to temporarily remove the state of negative pressure on operation in which a section near the surface of the substrate to be treated is brought to the state of negative pressure. CONSTITUTION:When the ashing treatment of a semiconductor wafer 14 is completed, a changeover valve 26 is changed over to the gas supply source 30 side, the outflow of an ashing gas is also stopped while a gas supply valve 28 is opened, and a gas from a gas supply source 30 is flowed out into a treating chamber 11 from a gas orifice 23 and a gas orifice 27. When an upper chamber 13 is lifted by an elevator 34, suction force A is generated. Consequently, the gas a flow rate of which is controlled so as to offset suction force is flowed out from a gas flow controller 29 regarding suction force generated by the state of negative pressure generated between a gas diffusing plate 24 and the semiconductor wafer 14 at that time. Since suction force is removed, force lifting the semiconductor wafer 14 from a base plate 15 does not work. Accordingly, the position of the semiconductor wafer 14 on the base plate 15 is not displaced.

Title: Magnetic recording circuit
Inventor: OKADA SHIGERU
IPC: G11B5/027
Filed: 1978-03-31
Abstract: PURPOSE: To perform recording of less distortions and reduce the output of a bias oscillator by adding the recording signal and bias signal and driving a recording head through a constant voltage driving type recording amplifier.  
     CONSTITUTION: The recording signal through an HPF 8 and the bias signal outputted from a bias oscillator 5 are added. This signal is then amplified in a constant voltage driving type recording amplifier 2 and is directly applied to a recording head 4. Hence, as compared to the case of driving the head by applying bias current through amplification of recording current, there is no need for bias trap, etc. and therefore the input voltage waveform of the head 4 becomes of the same waveform as that of the input voltage of the amplifier 2, thus the magnetic recording of less distortions may be accomplished. In addition, the bias signal is applied to the input signal before amplification and therefore the bias oscillator 5 can be one of smaller outputs.

IPC: H01P1/18
Filed: 1986-02-20
Abstract: PURPOSE:To reduce the entire size of a phase shifter by increasing the impedance of a microstrip line so as to narrow the width of the microstrip line. CONSTITUTION:The impedance of the microstrip lines 3, 4 is increased more than the impedance Z0 of an external line connected to an input and an output terminal of the phase shifter. Switch circuits 2, 2a change over the input and output sides of the lines 3, 4 respectively. Impedance matching circuits 1, 1a match the impedance Z of the lines 3, 4 with the impedance Z0 of the external line. Thus, the width of the lines 3, 4 is narrowed and the entire size of the phase shifter is reduced.

Title: Rolling bearing
Inventor: UCHIDA HIROYUKI
IPC: F16C33/76
Filed: 1998-02-19
Abstract: PROBLEM TO BE SOLVED: To improve the waterproof property and the dust-proof property without requiring a large space by fitting an annular shield plate to cover a seal outside in the axial direction of the seal and with intervals. SOLUTION: A rolling bearing 1 comprises an inner ring 2 fitted to a shaft 7, an outer ring 3 fitted to a housing 8, a ball 4 provided between the inner and outer rings, and a seal 5 fitted between the inner and outer rings. A flat metallic shield plate 6 is held and fitted between a flat surface of the inner ring 2 and a stop ring 9 outside in the axial direction of the seal 5. Thus, the seal itself is not directly collided with water or foreign matters, and because the shield plate 6 is opposite to the seal 5 with intervals therebetween, a labyrinth is formed between the seal 5 and the shield plate 6. Thus, even if water or foreign matters enter between the seal 5 and the shield plate 6, they are scattered by the centrifugal force. No large space is increased because the rolling bearing itself and its peripheral structure are not improved.
